Internal gear tooth quenched single row ball slewing ring bearing from excavator 




Slewing bearings are a large bearing capable of withstanding integrated loads and can withstand large axial, radial and overturning moments.


The slewing bearing of a light excavator is easily damaged. Usually the replacement cycle is 2 to 3 years. In this case, the main bearing failure is the broken teeth of the slewing ring, abnormal noise when rotating or the slewing ring is stuck. When this happens, stop the operation immediately, otherwise the rotating motor may be damaged.

Objectively, it is unfair to put all the blame on the bearing quality, because the slewing ring of the light excavator has a large rotation radius. Overwork is sometimes required, causing the teeth to wear and eventually break. In addition, the operation method of the excavator driver will also affect the service life of the slewing bearing.
